Rapid Fabrication of Low Impedance, 3D Dry Electrodes for Physiological Sensing [PDF]
arXiv, 2022 Medical electrophysiological sensors that can study the body and diagnose diseases depend on consistently low impedance electrode-skin interfaces. Clinical-standard wet electrodes use hydrogels and skin abrasion to improve the interface and thus the recorded signal quality.

Curvature affects electrolyte relaxation: studies of spherical and cylindrical electrodes [PDF]
Phys. Rev. E 100, 042602 (2019), 2019 With two minimal models, I study how electrode curvature affects the response of electrolytes to applied electrostatic potentials. For flat electrodes, Bazant et al. [Phys. Rev. E. 70, 021506 (2004)] popularized the "RC" timescale $\lambda_{\textrm{D}} L/D$, with $\lambda_{\textrm{D}}$ being the Debye length, $2L$ the electrode separation, and $D$ the ...

Li-diffusion accelerates grain growth in intercalation electrodes: a phase-field study [PDF]
Phys. Rev. Materials 3, 065404 (2019), 2018 Grain boundary migration is driven by the boundary's curvature and external loads such as temperature and stress. In intercalation electrodes an additional driving force results from Li-diffusion. That is, Li-intercalation induces volume expansion of the host-electrode, which is stored as elastic energy in the system. This stored energy is hypothesized

An Experimentally-Validated 3D Electrochemical Model Revealing Electrode Manufacturing Parameters Effects on Battery Performance [PDF]
arXiv, 2022 Electrode manufacturing is at the core of the lithium ion battery (LIB) fabrication process. The electrode microstructure and the electrochemical performance are determined by the adopted manufacturing parameters. However, in view of the strong interdependencies between these parameters, evaluating their influence on the performance is not a trivial ...
